The key parameters of the compressor are listed in Table 2. In the reversed cycle, the reverse logic applies and it will be found that more energy is given out at the condenser and more absorbed in the evaporator, than is needed to drive the compressor. From stage 1 to stage 2, the enthalpy of the refrigerant stays approximately constant, thus . A machine which takes in air or gas during suction stroke at low pressure and then compresses it to high pressure in a piston – cylinder arrangement is known as a reciprocating compressor. In the reversed cycle, the reverse logic applies and it will be found that more energy is given out at the condenser and more absorbed in the evaporator, than is needed to drive the compressor.
